A friend of mine was at LAX getting ready to leave for a business trip. She was having a cup of coffee at Starbucks and thinking about her presentation the next day.
Suddenly, all flights were cancelled and police officers were telling everyone to leave the airport. She had no idea why.
Her husband called her cell phone and said "Leave LAX. Forget your luggage. Just leave and come straight home." It wasn't until she was in her car going home that she heard about the terrorist attacks on the radio.
Later, she learned that the CEO of her company was on the flight that crashed into the Pentagon.
